We are currently using nLockTime for share info and nSequence for extranonce2. I have carefully reviewed the reference implementation of BIP68 and it should be compatible, but this proposal may break the implementation unless it does not affect coinbase transactions. On Fri, Sep 18, 2015 at 2:41 A

Re: [bitcoin-dev] Upcoming Transaction Priority Changes

2015-11-12 Thread Chun Wang via bitcoin-dev
I doubt changing the default value is useful as casual mining had long dead, and pools all have their own customized policies. But I think change the priority size to 0 is the right way to do. The sort by priority part in the block is always the best place for spam nowadays. I would think about to

Re: [bitcoin-dev] BIP - Block size doubles at each reward halving with max block size of 32M

How about these specs: * 1 MB, height < 21; * 2 MB, 21 <= height < 42; * 4 MB, 42 <= height < 63; * 8 MB, 63 <= height < 84; * 16 MB, 84 <= height < 105; * 32 MB, height >= 105. On Fri, Nov 13, 2015 at 7:47 AM, John Sacco via bitcoin-dev wrote: > Hi Devs,

[bitcoin-dev] The increase of max block size should be determined by block height instead of block time

In many BIPs we have seen, include the latest BIP202, it is the block time that determine the max block size. From from pool's point of view, it cannot issue a job with a fixed ntime due to the existence of ntime roll. It is hard to issue a job with the max block size unknown. For developers, it is

Proposal 1 looks good, but tx fee collected can be manipulated by miners. I like the idea next block collect the tx fee from previous block. On Tue, Aug 25, 2015 at 5:07 PM, Upal Chakraborty via bitcoin-dev wrote: > Github: > https://github.com/UpalChakraborty/bips/blob/master/BIP-DynamicMaxBlock
